Elektriese instandhouding van enkelbalk oorhoofse hyskraan

In order to ensure the reliable and safe operation of single girder overhead crane. It is necessary to formulate an electrical equipment maintenance system that meets the requirements of "GB6067-85". And be familiar with the causes of various failures of the equipment and the methods to eliminate them.

The maintenance of the main electrical equipment is described below.

In order to increase the service life of crane electrical equipment, the contactors in the electrical equipment control box should be kept clean to prevent leakage breakdown and short circuit (current does not pass through the electrical appliances, directly connected to the power supply poles) and other phenomena.

When the electrical cable is used to conduct electricity. The corner rust and dirt on the slide rail of the trolley should be removed at any time to keep the traction pulley running normally.
